Answer: 4.8

Step-by-step explanation:0.6*5+0.6*1 1/2*2

Answer:

When we have  a set of N numbers like:

{x₁, x₂, ..., xₙ}

The mean of the set is:

M = (x₁ + x₂ + ... + xₙ)/N

In this case, we have the set:

{250, 280, 265, 245, 270, 255, 290}

So we have a set of 7 elements.

The mean of this set will be:

M = (250 + 280 + 265 + 245 + 270 + 255 + 290)/7 = 1855/7 = 265

So the mean number of stomata per mm of leaf surface is 265.

Answer:

Your answer is indeed correct.   f(-8) = 3

Step-by-step explanation:

[tex]f(x) = -x^{2} - 4x + 35\\f(-8) = -( -8)^{2} - 4(-8) + 35\\f(-8) = -64 + 32+ 35\\f(-8) = 3[/tex]

Answer:

The headphones are now $40.60.

Given :

▪︎Length of height of this triangle = 16 cm

▪︎Length of base of this triangle = 4 cm

We know that :

[tex]\color{hotpink}\tt \: area \: of \: a \: triangle \color{plum}= \frac{1}{2} \times base \times height[/tex]

Which means :

The area of this triangle :

[tex] = \tt \frac{1}{2} \times 16 \times 4[/tex]

[tex] =\tt \frac{1}{2} \times 64[/tex]

[tex] = \tt \frac{64}{2} [/tex]

[tex]\color{plum} =\tt\bold{ 32 \: {cm}^{2} }[/tex]

▪︎Therefore, the area of this triangle = 32 sq.cm

Answer:

2/3

Step-by-step explanation:

Answer:

[tex](9x^3y^2)^2[/tex]

Step-by-step explanation:

The expression, as a square of a monomial, will be given by:

[tex](\sqrt{81x^6y^4})^2[/tex]

Now, we calculate the root, applying it's properties. So

[tex]\sqrt{81x^6y^4} = \sqrt{81} \times \sqrt{x^6} \times \sqrt{y^4} = 9 \times x^{\frac{6}{2}} \times y^{\frac{4}{2}} = 9x^3y^2[/tex]

The expression as a square of a monomial is given by

[tex](9x^3y^2)^2[/tex]

Answer:

30, 39, 48

Step-by-step explanation:

5 hours is 30 because of 24 + 6

6.5 hours is 39 because 30 + 6 + 3

8 hours is 48 because 39 + 6 + 3

Answer:

77 pots

Step-by-step explanation:

To find how many pots he washes in 1 3/4 hours, multiply 44 by 1.75, since

3/4 = 0.75.

44(1.75)

= 77

So, Randy can wash 77 pots in 1 3/4 hours

Answer:

77

Step-by-step explanation:

He washes 11 every quarter of an hour, so just add 33 to 44

Answer:

x = 142°

Step-by-step explanation:

Since angle x and the 38° angle are supplementary angles, we know that the following is true...

x + 38° = 180°

x = 180° - 38°

x = 142°

Answer:  I think the answer is 32.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Suppose there is the addition of a constant "b" to each generic dataset, then, new mean = old mean + b. This will affect the variance and the standard deviation of the resulting dataset to remain the same:

From the information given:

[tex]\mathbf{x_1,x_2,x_3...x_n \ have \ mean \ \overline x }[/tex]

Proof:

If c is added to each data set:

Then,

[tex]\mathbf{x_1+c,x_2+c,x_3+c...x_n+c \ and \ the \ new \ mean \ \overline x = \overline x + c}[/tex]

also;

[tex]\mathbf{New \ Sd^2 = \dfrac{(x_1+c -(\overline x+c))^2+ (x_2+c -(\overline x+c))^2 +...+ (x_3+c -(\overline x+c))^2}{n}}[/tex]

[tex]\mathbf{New \ Sd^2 = \dfrac{(x_1+c -\overline x+c)^2+ (x_2+c -\overline x+c)^2 +...+ (x_3+c -\overline x+c)^2}{n}}[/tex]

[tex]\mathbf{New \ Sd^2 = (x_1- \overline x)^2+ (x_2- \overline x)^2+ ... +(x_n- \overline x)^2}[/tex]

[tex]\mathbf{New \ Sd^2 = old \ sd^2}[/tex]

Answer:

Step-by-step explanation:

you can use fraction strips by using them 3/4 and 6/8 because they are equivalent  and that's just life :)

3/4 and 6/8 are equivalent numbers/fractions

The fractions are given as:

[tex]\frac 34[/tex] and [tex]\frac 68[/tex]

To model 3/4 using number lines, we do the following steps

To model 6/8 using number lines, we do the following steps

When both points are compared, then we find out that:

[tex]\frac 34 \equiv \frac 68[/tex]

Hence, 3/4 and 6/8 are equivalent

Answer:

14/33

Step-by-step explanation:

Okay so first of all, we want to find the probability of picking that first purple marble. There are 8 purple marbles you can chose out of a possible 12 marbles, so the probability is 8/12, or 2/3.

Next, find the probability of finding the second purple marble. Since you took out one purple marble already, there are 7 purple marbles you could chose out of a possible 11 marbles, so the probability is 7/11.

To find out the probability of both of these events happening, you multiply these probabilities:

[tex]\frac{2}{3} * \frac{7}{11}\\\frac{2*7}{3*11} \\\frac{14}{33}[/tex]
